Answer:

chemical heat and mechanical in that order

Step-by-step explanation:

Answer: Chemical - Heat - Mechanical.

Step-by-step explanation:

An internal combustion engine, such as a gasoline engine, converts the chemical energy in fuel to the propulsive energy that moves a car. When gasoline combusts, heat energy is produced and converted to mechanical energy that allows a car to move.

While light energy is also produced along with heat energy during the conversion of chemical energy to mechanical energy, the light energy does not have any effect on the movement of the car.

Answer:

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

To find x subtract the sum of the 2 given angles from 180, that is

x = 180° - (32 + 52)° = 180° - 84° = 96°

-------------------------------------------------------

x and y form a straight angle, hence

y = 180 - x = 180° - 96° = 84°

------------------------------------------------------

To find z subtract the sum of the 2 angles from 180

z = 180° - (55 + y)° = 180° - (55 + 84)° = 180° - 139° = 41°

--------------------------------------------------------

x = 96°, y = 84°, z = 41° → A

Final answer:

The sum of the functions [tex]F(x) = 2^x + 5x[/tex] and g(x) = 3x - 5 is [tex](f+g)(x) = 2^x + 8x - 5[/tex], which is obtained by adding the corresponding elements of each function and combining like terms.

Explanation:

The question asks for the sum of two functions, F(x) and g(x). In mathematical terms, (f+g)(x) means we have to add the functions F(x) and g(x) together. This is done by adding the corresponding elements of each function.

Here are the given functions:

F(x) = 2x + 5x

g(x) = 3x - 5

To find (f+g)(x), we combine them like this:

(f+g)(x) = F(x) + g(x) = (2x + 5x) + (3x - 5)

Now, we simply combine like terms:

(f+g)(x) = 2x + 5x + 3x - 5

(f+g)(x) = 2x + 8x - 5

This is the simplified form of the sum of the functions F(x) and g(x).

Final answer:

To find (f+g)(x) where f(x)=2ˣ + 5x and g(x)=3x-5, you simply add the functions together to get (f+g)(x) = 2ˣ + 8x - 5.

Explanation:

The student has asked to find (f+g)(x) where f(x) = 2ˣ + 5x and g(x) = 3x - 5.

To find (f+g)(x), we add the two functions together:

So, (f+g)(x) is:

(f+g)(x) = (2ˣ + 5x) + (3x - 5)

Combine like terms:

(f+g)(x) = 2ˣ + 5x + 3x - 5

(f+g)(x) = 2ˣ + 8x - 5

That is the simplified form of the function (f+g)(x).

Answer:

Step-by-step explanation:

Yur Welcome

The answer to the question [tex]\( \frac{12}{2/3} \) is \( 18 \).[/tex]

To solve the expression [tex]\( \frac{12}{2/3} \)[/tex], need to divide 12 by [tex]\( \frac{2}{3} \).[/tex] Dividing by a fraction is the same as multiplying by its reciprocal. Therefore, we can rewrite the expression as:

[tex]\[ 12 \times \frac{3}{2} \][/tex]

Now, multiply 12 by \( \frac{3}{2} \):

[tex]\[ 12 \times \frac{3}{2} = \frac{12 \times 3}{2} \][/tex]

[tex]\[ \frac{12 \times 3}{2} = \frac{36}{2} \][/tex]

Finally, divide 36 by 2 to get the result:

[tex]\[ \frac{36}{2} = 18 \][/tex]

So, [tex]\( \frac{12}{2/3} = 18 \)[/tex]. This is the value you would use if this calculation appears on your module exam.

Answer:

[tex]\frac{1}{2}(\frac{1}{4}^x)[/tex]

Step-by-step explanation:

To find the function, compare the y values. Notice that each y value decreases by being divided by 4. This means the base of the exponential is 1/4.

To find the initial value, consider the point (0,0.5). When 1/4 is raised to the 0 power, the value is 1. This leaves that the initial value is 1/2 since 1/2*1 = 0.5.

The function is [tex]\frac{1}{2}(\frac{1}{4}^x)[/tex].

Answer:

The required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

Step-by-step explanation:

The general exponential function is

[tex]f(x)=ab^x[/tex]           .... (1)

where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (0,0.5) and (-1,2). It means the equation of function must be satisfied by the points (0,0.5) and (-1,2).

Substitute f(x)=0.5 and x=0 in equation (1), to find the value of a.

[tex]0.5=ab^0[/tex]

[tex]0.5=a[/tex]

The value of a is 0.5.

Substitute a=0.5, f(x)=2 and x=-1 in equation (1), to find the value of b.

[tex]2=(0.5)b^(-1)[/tex]

[tex]2=\frac{0.5}{b}[/tex]

[tex]2b=0.5[/tex]

Divide both sides by 2.

[tex]b=\frac{0.5}{2}[/tex]

[tex]b=0.25[/tex]

The value of b is 0.25.

Substitute a=0.5 and b=0.25 in equation (1).

[tex]f(x)=0.5(0.25)^x[/tex]

[tex]f(x)=\frac{1}{2}(\frac{1}{4})^x[/tex]

Therefore the required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

ANSWER

C. If it is not night, then the street lights will not come on.

EXPLANATION

The given statement is

"If it is night, then the street lights will come on"

Given the statement,

"If p, then q",

then the inverse of this statement is

"If it is not night,then the street lights will not come on"

"If not p, then not q"

The correct choice is C.

The inverse of a conditional statement is created by negating both the hypothesis and the conclusion. Thus, the inverse of the statement 'If it is night, the street lights will come on.' is 'If it is not night, then the street lights will not come on.'

The question is asking for the inverse of a given statement. In logic, the inverse of a conditional statement is created by negating both the hypothesis and the conclusion. The original statement: 'If it is night, the street lights will come on.' becomes 'If it is not night, then the street lights will not come on.' in its inverse form. So, the correct answer is C. If it is not night, then the street lights will not come on.

Answer:

4 units

Step-by-step explanation:

X coordinate never changed so you just need to subtract 2 from 8 to see the unit difference.

The distance between the two points (-6, 2) and (-6, 8) on a coordinate plane is 6 units, as they share the same x-coordinate, and the distance can be found by the absolute value of the difference in y-coordinates.

The distance between two points on a coordinate plane can be determined by finding the absolute difference between their x-coordinates if they share the same x-coordinates or their y-coordinates if they share the same y-coordinates. Since the points (-6, 2) and (-6, 8) share the same x-coordinate, we can subtract the y-coordinates to find the distance:

Distance = |y2 - y1|
= |8 - 2|
= |6|
= 6 units

Therefore, the distance between the two points located at (-6, 2) and (-6, 8) on a coordinate plane is 6 units.

Answer:

Step-by-step explanation:

[tex]-x=2-3x+6\qquad\text{add}\ 3x\ \text{to both sides}\\\\-x+3x=8-3x+3x\\\\2x=8\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{8}{2}\\\\x=4[/tex]

Answer:

Im not sure about the other 2 but the last box is 12, the answer above is incorrect for PLATO. I just took the test.

The y-intercept of line AB is 0, and the equation of line CD is y = 5.

The y-intercept of a line is the point where it intersects the y-axis. In this case, we are given the coordinates of point A as (8, 0). Since the y-coordinate of point A is 0, the y-intercept of line AB is 0.

The equation of a line can be determined using the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. The slope of line CD can be found by finding the difference in y-coordinates divided by the difference in x-coordinates between points C and D. In this case, the slope is (5 - 5) / (5 - 5) = 0. Therefore, the equation of line CD is y = 0x + b, where b is the y-intercept. Since point D has coordinates (5, 5), the y-intercept is 5. Therefore, the equation of line CD is y = 0x + 5, or simply y = 5.

r=rate = 26.9%=0.269

\text{Exponential Decay:}

Exponential Decay:

Put it all together

\text{Plug in time for x:}

Plug in time for x:

y= 7.091174

y=7.091174

Evaluate

y\approx 7.1

y≈7.1

round

To calculate the remaining amount of an element undergoing exponential decay, use the formula A = A0 * (1 - r)^t, where A is the remaining amount, A0 is the initial amount, r is the decay rate per minute, and t is the time in minutes. In this case, approximately 12.3 grams of the element is remaining after 14 minutes.

To calculate the amount of the element remaining after 14 minutes, we need to use the formula for exponential decay, which is A = A0 * (1 - r)t, where A is the remaining amount, A0 is the initial amount, r is the decay rate per minute (in decimal form), and t is the time in minutes.

In this case, the initial amount is 570 grams, the decay rate is 26.9% or 0.269 per minute, and the time is 14 minutes.

Plugging these values into the formula, we get:

A = 570 * (1 - 0.269)14 = 570 * (0.731)14 = 570 * 0.0221 = 12.27 grams.

Therefore, approximately 12.3 grams of the element is remaining after 14 minutes.

(12/7, 9/7)

Since y = -x + 3, substitute it into the first equation.

-x + 3 = 5/2x - 3

Now add x and subtract 3 from both sides.

0 = 7/2x - 6

Now add 6 on both sides.

6 = 7/2x

Now divide by 7/2 on both sides.

12/7 = x

2x + 3y = 20

Step-by-step explanation:

Slope of the line is -2/3 .  We can use any of the given points to find the equation of the line. Lets use (1, 6)

The general point-slope form of a line is:

[tex]y-y_{1} =m(x-x_{1} )[/tex]

Here m is the slope which is -2/3

x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6

Using these values, we get:

[tex]y-6=-\frac{2}{3} (x-1)\\\\ 3(y-6)=-2(x-1)\\\\ 3y-18=-2x+2\\\\ 2x+3y=20[/tex]

Answer:

2x + 3y = 20

Step-by-step explanation:

We are given two points: (–2, 8) and (1, 6) and the slope (m) of the line and we are to find the equation of this line.

We know that the standard equation of a line is:

[tex]y=mx+c[/tex]

So we will plug in the given values in the above equation to find the y intercept.

[tex]6=-\frac{2}{3} (1)+c[/tex]

[tex]c=\frac{20}{3}[/tex]

So the equation of this line will be:

[tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
